Terms in this Study Set(19)
Quadriceps Femoris
A group of four muscles at the front of the thigh. They extend the knee and are essential for walking, running, and jumping.
Hamstring Group
Three muscles at the back of the thigh. They flex the knee and extend the hip, important for running and jumping.
Gastrocnemius
A major calf muscle with two heads. It aids in plantarflexion of the foot and flexion of the knee.
Soleus
Located beneath the gastrocnemius. It also contributes to plantarflexion, playing a key role in standing and walking.
Tibialis Anterior
Located at the front of the leg. It dorsiflexes the foot and helps prevent foot drop during walking.
Adductor Muscles
Group of muscles on the inner thigh. Responsible for adducting the thigh and stabilizing the hip joint.
Gluteus Maximus
The largest muscle in the buttocks. It extends and externally rotates the hip, crucial for powerful movements.
Pectineus
Located in the upper thigh. It adducts and flexes the hip, playing a role in leg movements.
Rectus Femoris
Part of the quadriceps group. It flexes the hip and extends the knee, involved in walking and running.
Biceps Femoris
One of the hamstring muscles. It flexes the knee and assists in hip extension.
True or false: The hamstrings extend the knee.
False, because they flex the knee.
Difference between gastrocnemius and soleus
Gastrocnemius has two heads and crosses the knee, while soleus is flat and does not.
Fill in the blank: The ___ muscle helps with dorsiflexion.
Tibialis Anterior.
What is the primary function of quadriceps?
To extend the knee.
Gluteus Medius
Located on the outer surface of the pelvis. It abducts the thigh and stabilizes the pelvis during walking.
True or false: The adductor group is located on the outer thigh.
False, they are located on the inner thigh.
What muscle is primarily responsible for the plantarflexion of the foot?
Gastrocnemius.
Muscles involved in hip extension
Gluteus Maximus, Hamstrings.
Which muscle is used in running?
Quadriceps Femoris and Hamstring Group.
